MIL-DTL-38999 Series IVFor missile launch controls and other severe vibration applicationsFrom vertical launch fire-control, tracking, and multi-target missile systems to rugged
industrial applications such as mining/gas-pressure blasting, the Glenair’s DLA qualified MIL-DTL-38999 Series IV connector is the ultimate solution for positive and reliable breech-locking connector performance. MIL-DTL-38999 Series IV plug and receptacle connectors are available in shell sizes 11–25, with all Mil-Std 1560 insert arrangements as well as high-density and hybrid shielded contact arrangements. The heart of the Series IV connector is its coupling nut/locking technology which provides rock solid breech-lock mating augmented with both primary and secondary locking mechanisms. Environmentally sealed, EMI grounded, and outfitted with pin-to-pin mating protection to prevent circuit shorts and mechanical damage, Glenair MIL-DTL-38999 Series IV QPL connectors deliver unsurpassed reliability and anti-demating performance.

SERIES IV HERMETICSMECHANICAL AND ELECTRICAL PERFORMANCE
MIL-DTL-38999 Series IV (and Glenair Series 234-105) offers outstanding interconnect performance for high shock and vibe military and commercial applications.
�� Breech locking connectors with crimp contacts
�� Electromagnetic compatibility (EMC): metal-to-metal coupling, plug grounding fingers, and conductive shell finishes deliver excellent shielding performance up to 65 dB at 10 GHz. Grounding occurs before engagement of contacts.
�� Contact protection: scoop-proof design prevents inadvertent damage to pin contacts during mating
�� Corrosion resistance: connector shells are made from corrosion-resistant aluminum and are offered with cadmium or electroless nickel finish
�� Supported contacts: from size #22D signal to #12 shielded Coax
�� Glenair COTS versions offer equivalent performance with material/finish options not available in QPL parts
